If this function returns [code]true[/code], the generator will call [method _generate] or [method _generate_from_path] for small previews as well.
|
|
By default, it returns [code]false[/code].

Generate a preview from a given resource with the specified size. This must always be implemented.
|
|
Returning an empty texture is an OK way to fail and let another generator take care.
|
|
Care must be taken because this function is always called from a thread (not the main thread).

Generate a preview directly from a path with the specified size. Implementing this is optional, as default code will load and call [method _generate].
